COLLABORATIVE NETWORK ON ATMOSPHERIC ENVIRONMENTAL POLICES IN CHINA'S THREE MAJOR URBAN AGGLOMERATIONS
Collaborative harness of atmospheric pollution requests acoalition among local governments,which is marked by a jointly-issued environmental policies.This paper,based on official 2009 to 2019 atmospheric environmental policies,uses social network analysis(SNA)and Gephi software to map their network relationship graph among departments,and employs Ucinet to analyze their density and centrality of department collaboration in Beijing-Tianjin-Hebei,Yangtze River Delta and Chengdu-Chongqing urban agglomerations,exploring their coordination among governmental departments during environmental harness.In Beijing-Tianjin-Hebei urban agglomeration,Beijing has the most extensive atmospheric environmental policies with most departments involved and frequent coordination.Tianjin has the fewest departments involved in making atmospheric environmental policies but with premium internal department coordination.Hebei has the less policy quantities and departments,which shall be further boosted.In Yangtze River delta urban agglomeration,Shanghai has a few atmospheric environmental policies,but with most departments involved and most frequent cooperation.Zhejiang has the most policies with extensive departments involved,less in department coordination.Jiangsu is quite similar with Anhui in policy quantities and involving departments,but Anhui has the least department coordination.In Chengdu-Chongqing urban agglomeration,Chongqing has less policies,less involving departments with little cooperation.Sichuan performs better,but has yet formed a collaborative network mode among departments with"polar-kernel"features.This paper presents suggestions on fulfilling functions of urban agglomeration to establish communicating channels among regional governments and organizations and to form a multiple-department-involving and diversified normalized mechanism in harnessing atmospheric pollution.
